Performance Improvements

6u18 introduces improvements in the following areas:

  • Faster jar File Creation

    The fix of a long standing bug related to jar file creation has greatly improved creation time. For example, for a given jar file, it is possible that you might see a creation time improvement in the range of 20 percent. (Refer to 6496274.)

  • Java Hotspot VM 16.0

    6u18 includes version 16.0 of the Java HotSpot Virtual Machine. Contributing to increased performance in this release are several enhancements in Java HotSpot VM 16.0. These include:

    • Improved NUMA-aware allocation
    • Extensions to compressed object pointers


    • Garbage collection improvements
      • Updated Client JVM heap configuration

        In the Client JVM, the default Java heap configuration has been modified to improve the performance of today's rich client applications. Initial and maximum heap sizes are larger and settings related to generational garbage collection are better tuned.

        • The default maximum heap size is half of the physical memory up to a physical memory size of 192 megabytes and otherwise one fourth of the physical memory up to a physical memory size of 1 gigabyte.
          For example, if your machine has 128 megabytes of physical memory, then the maximum heap size is 64 megabytes, and greater than or equal to 1 gigabyte of physical memory results in a maximum heap size of 256 megabytes.
        • The maximum heap size is not actually used by the JVM unless your program creates enough objects to require it. A much smaller amount, termed the initial heap size, is allocated during JVM initialization. This amount is at least 8 megabytes and otherwise 1/64 of physical memory up to a physical memory size of 1 gigabyte.
        • The maximum amount of space allocated to the young generation is one third of the total heap size.
        • The updated heap configuration ergonomics apply to all collectors except Concurrent Mark-Sweep (CMS). CMS heap configuration ergonomics remain the same.
        • Server JVM heap configuration ergonomics are now the same as the Client, except that the default maximum heap size for 32-bit JVMs is 1 gigabyte, corresponding to a physical memory size of 4 gigabytes, and for 64-bit JVMs is 32 gigabytes, corresponding to a physical memory size of 128 gigabytes.

      • Work stealing termination
      • Work queue overflow processing
      • Bit set processing on 64-bit Linux


    • Class loading optimizations for faster startup (see Bug Fixes section)


    • Code generation improvements
      • New intrinsics using SSE 4.2
      • New intrinsics for Integer/Long bit operations - leading/trailing zeros, bit count
      • Unsigned byte and integer loads
      • Integer load shortening
      • Elision of needless conversions between integer primitive types
      • Optimization of common string concatenation patterns


    • Garbage First (G1) garbage collector

      For more information about G1, see the G1 technology page.

    In addition to performance enhancements, HotSpot VM 16.0 offers improved reliability and serviceability.

    • Serviceability enhancements
      • New options to request a heap dump or class histogram before or after a full GC
      • New tool to decode LogCompilation output


    • Extensive reliability improvements (see Bug Fixes section)

    • Note that Escape analysis-based optimization ( -XX:+DoEscapeAnalysis) is disabled in 6u18. This option will be restored in a future Java SE 6 update.


  • Application Startup Improvements
    • Better startup of applications and applets on systems where D3D is used. Savings are up to 100-200ms depending on application and the system. (Refer to 6891435.)
    • Revised support for pre-verification of FX runtime. Improves warm start of typical FX applications by up to 15 percent. (Refer to 6894899.)
    • Concurrent download of jars for webstart applications and applets.
    • Number of other startup improvements for UI applications and applets. (Refer to 6753173, 6896857, 6892138, 6868503, 6874881, 6874336, 6891293 and 6895250.)


  • Runtime Performance Improvements for UI Applications
    • Improved performance of applications using translucent windows. (Refer to 6794764.)
    • Better performance and smaller memory consumption by text rasterizer. (Refer to 6891557 and 6891551.)
    • Faster processing of PNG images. (Refer to 6549882.)


  • Ability to Read Larger .zip Files

    As of this update release, it is possible to read .zip files of sizes up to 4 gigabytes. (Refer to 6860950.)


Deployment Updates
Java Web Start
Java Web Start now implements JSR-056 version 6.0.18. See jcp.org for updated specification.

This release introduces the following features that enhance the capabilities of Java Web Start applications:



  • New JNLP Extension Security Dialog

    A new security dialog has been introduced in 6u18 for installing signed Java extensions on a user's system. Java extensions are components described in JNLP files that are typically intended to be used by a large number of applications and applets.

    The new security dialog is triggered by an application that references the Java extension in its JNLP file (by including it in the resources element). The security dialog will ask the user if they would like to install the extension. Once the extension is installed, it can be referenced by other applications without the need for asking the user's permission again (as long as it is the same extension from the same codebase).

    The JNLP file of the Java extension must adhere to the following requirements:
    • The JNLP file MUST contain a component-desc element that describes the Java extension.
    • The JAR files that are specified in the resources element MUST be signed with the same certificate.
    • The signer's certificate MUST contain an Authority Information Access or CRL Distribution Points extension so that the revocation status can be checked (via OCSP or CRLs).
    Here is an example of the new security dialog.


JSR-173 StAX 1.2 API Upgrade

6u18 includes an upgrade to minor revision 1.2 of JSR-173 Streaming API for XML (StAX) which was a result of Maintenance Reviews 2 and 3. You can find more details about these Maintenance Reviews in the JSR 173 Change Log. Also refer to 6861589.

The StAX 1.2 upgrade maintains binary and source compatibility. Existing binaries compiled on StAX 1.0 will continue to run on StAX 1.2. Programs written to StAX 1.0 will continue to compile to StAX 1.2.

There will be a minor behavioral difference if deprecated methods are used. In this case, there will be deprecation warnings at compilation. Other than these warning messages, the StAX 1.2 upgrade maintains behavioral compatibility.



Known Issues


  • The Java Install Issue
  • When installing Java on a 64 bit Windows system, the 64 bit javaws becomes the default handler even if the 32 bit version were already installed. This will cause all 32 bit only applications (like JavaFX) to fail when 64 bit Java was installed last (after 32 bit Java). This issue applies to any JNLP based applications.

    The workaround for this issue is to install the 64-bit version of Java first, and then install the 32-bit version of Java. If they were installed in the other order, then reinstalling the 32-bit version of Java will fix.

    Refer to 6909619.

  • Card-Marking Optimization Issue
  • A flaw in the implementation of a card-marking performance optimization in the JVM can cause heap corruption under some circumstances. This issue affects the CMS garbage collector prior to 6u18, and the CMS, G1 and Parallel Garbage Collectors in 6u18. The serial garbage collector is not affected. Applications most likely to be affected by this issue are those that allocate very large objects which would not normally fit in Eden, or those that make extensive use of JNI Critical Sections (JNI Get/Release*Critical).

    This issue will be fixed in the next Java SE 6 update.

    Meanwhile, as a workaround to the issue, users should disable this performance optimization by -XX:-ReduceInitialCardMarks.

    Refer to 6896647 and 6888898.
